just bought house which has a single cable running from main fuse box to a separate fuse box which in turn runs a ring main of sockets. I think this should be converted to a ring running off the main box and do away with the second fuse box. If it's ok to leave as is then what cable size should the "spur" between the fuse boxes be? and what rating should the breakers be?

What size fuse in the first fuse box protects the wiring to the second fuse box? (Or is the cable just tapped into the main incoming terminals?)
You can have as many sockets as you like on a ring circuit, assuming everything else about it is as it should be.
It's strange the ring isn't wired directly into the first fuse box. Perhaps the second box provides RCD protection.
I would expect to see the cable feeding the second box to be at least 4 mm. Or 6 mm.
PICTURES can be sent, if in doubt.

I would recommend you check you have RCD protection on the socket circuit before you do anything. There must be a reason it was wired in this way, I'd have thought...
Any of the devices related to this circuit have 30 mA printed on them?
